COPD exacerbation and antibiotics

OBJECTIVES: The clinical significance of Stenotrophomonas maltophilia in patients with COPD is poorly understood. We aimed to determine whether a lower respiratory tract culture positive for S. maltophilia in COPD patients was independently associated with increased risk of death and hospitalisation for exacerbation of COPD. METHODS: An observational cohort study following outpatients with COPD in Eastern Denmark between 2010 and 2018, with a follow-up period of five years...

BACKGROUND: Non-ventilator-associated ICU-acquired pneumonia (NV-ICU-AP), a nosocomial pneumonia that is not related to invasive mechanical ventilation (IMV), has been less studied than ventilator-associated pneumonia, and never in the context of patients in an ICU for severe acute exacerbation of chronic obstructive pulmonary disease (AECOPD), a common cause of ICU admission. This study aimed to determine the factors associated with NV-ICU-AP occurrence and assess the association between NV-ICU-AP and the outcomes of these patients...

Chronic obstructive pulmonary disease (COPD) is a common and debilitating condition that often necessitates hospitalization for exacerbations. Since COPD exacerbations can cause significant morbidity and mortality, managing them is crucial for patient care. Effective management of COPD exacerbations is essential to prevent complications, as COPD exacerbations are associated with increased healthcare costs and decreased quality of life. This review aims to comprehensively discuss the management of COPD exacerbations, covering various pharmacologic and non-pharmacologic strategies...

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a major cause of morbidity and mortality. Acute exacerbations of COPD (AECOPD) drastically affect the clinical course of the disease. We aimed to evaluate the treatment of AECOPD in the internal medicine departments in Israel, nationwide. METHODS: The COPD Israeli survey (COPDIS) is the first national survey of patients admitted with AECOPD to internal medicine departments between 2017 and 2019. The survey includes prospective ( n  = 344) and retrospective ( n  = 1,166) data from 13 medical centers...

BACKGROUND: Increasing studies have shown that the imbalance of the respiratory microbial flora is related to the occurrence of COPD, the severity and frequency of exacerbations and mortality.However, it remains unclear how the sputum microbial flora differs during exacerbations in COPD patients manifesting emphysema phenotype, chronic bronchitis with emphysema phenotype and asthma-COPD overlap phenotype. METHODS: Sputum samples were obtained from 29 COPD patients experiencing acute exacerbations who had not received antibiotics or systemic corticosteroids within the past four weeks...

PURPOSE: Acute exacerbation of chronic obstructive pulmonary disease (AECOPD) is a leading cause of deterioration in patients with otherwise stably controlled COPD. Treatments of AECOPD often require the use of corticosteroid therapy in conjunction with bronchodilators and antibiotics. However, the duration and dosage of corticosteroids still remain unclear. We propose to perform this systematic review and meta-analysis of all available randomized control trials (RCTs) and observational cohort studies to comprehensively assess the efficacy and safety of different corticosteroid duration and dosing regimen in the current body of evidence...

BACKGROUND: Use of inhaled corticosteroids (ICS) is common in patients with chronic obstructive pulmonary disease (COPD) and has been associated with an increased risk of pneumonia. Moraxella catarrhalis is one of the most common bacterial causes of infectious exacerbation in COPD. Currently, to our knowledge, no studies have investigated if ICS increases the risk of lower respiratory tract infection with M. catarrhalis in patients with COPD. OBJECTIVE: To investigate if accumulated ICS use in patients with COPD, is associated with a dose-dependent risk of infection with M...

Chronic obstructive pulmonary disease is a major health problem with a high prevalence, a rising incidence, and substantial morbidity and mortality. Its course is punctuated by acute episodes of increased respiratory symptoms, termed exacerbations of chronic obstructive pulmonary disease (ECOPD). ECOPD are important events in the natural history of the disease, as they are associated with lung function decline and prolonged negative effects on quality of life. The present-day therapy for ECOPD with short courses of antibiotics and steroids and escalation of bronchodilators has resulted in only modest improvements in outcomes...

In clinical practice, clinicians mainly focus on Chronic Obstructive Pulmonary Disease (COPD) exacerbations and symptoms, while patients may prefer to evaluate periods free of COPD exacerbations and deteriorated symptoms. The latter would suit the positive health approach that centralizes people and their beliefs. We aimed to identify patient characteristics and health outcomes relating to: 1) COPD exacerbation-free days; 2) days with no more symptoms than usual; and 3) combined COPD exacerbation and comorbid flare-up-free days (i...

Classically, the role of pulmonary infection in patients with chronic obstructive pulmonary disease (COPD) has focused on periods of exacerbation. However, in a clinically stable situation, little attention has been paid to the role play by the presence of potentially pathogenic micro-organisms (especially when they are repeatedly isolated, which is known as chronic bronchial infection [CBI]) in the pathogenesis, prognosis and disease treatment. In recent years, however, some evidence has been published on the deleterious effect of CBI in COPD since it has been associated to greater local inflammation, greater disease severity, poorer health-related quality of life, greater number and severity of exacerbations and cardiovascular events, presence of bronchiectasis, rapid decline of lung function, and even higher mortality (especially related to Pseudomonas aeruginosa infection)...

Chronic obstructive pulmonary disease (COPD) is one of the most common respiratory disorders in the world. Pharmacologic management of an acute exacerbation of COPD can be guided by the mnemonic ABC, for Antibiotics and anticholinergics, Beta2 adrenergic agonists, and Combination therapies and corticosteroids.

OBJECTIVE: The choice of steroids and antibiotics is optional for the management of acute exacerbation of chronic obstructive pul- monary diseases according to international guidelines. The study hypothesized that the steroid and antibiotic choice can be decided by using the neutrophil-lymphocyte ratio and peripheral blood eosinophilia in patients with acute exacerbation of chronic obstructive pulmonary diseases. This would reduce the rate of re-hospitalization in 28 days. MATERIAL AND METHODS: Patients were hospitalized due to acute exacerbation of chronic obstructive pulmonary diseases from February 1, 2018, to January 31, 2019...

Rationale: Chronic obstructive pulmonary disease (COPD) exacerbations are a major cause of morbidity and mortality, and preventing them is a key treatment target. Long-term macrolide treatment is effective at reducing exacerbations, but there is a paucity of evidence for other antibiotic classes. Objectives: To assess whether 12-month use of doxycycline reduces the exacerbation rate in people with COPD. Methods: People with moderate to very severe COPD and an exacerbation history were recruited from three UK centers and randomized to 12 months of doxycycline 100 mg once daily or placebo...

COPD is a progressive inflammatory process affecting both the airways and alveolar structures of the lungs. Exacerbations of COPD are episodes of acute worsening of this inflammatory process, often triggered by infections. The most severe exacerbations are characterized by substantial air trapping and inspiratory muscle overload, which leads to hypercapnic respiratory failure. Pharmacologic therapies focus on intense bronchodilator administration (usually by aerosol), corticosteroids, and antibiotics. Respiratory life support technologies are often needed for severe exacerbations and range from carefully titrated supplemental O2 administration to positive-pressure ventilation (both invasive and noninvasive)...

OBJECTIVES: Little is known about the recent status of acute exacerbation of chronic obstructive pulmonary disease (AECOPD) in the U.S. emergency department (ED). This study aimed to describe the disease burden (visit and hospitalization rate) of AECOPD in the ED and to investigate factors associated with the disease burden of AECOPD. METHODS: Data were obtained from the National Hospital Ambulatory Medical Care Survey (NHAMCS), 2010-2018. Adult ED visits (aged 40 years or above) with AECOPD were identified using International Classification of Diseases codes...

Patients with corticosteroid-managed chronic obstructive pulmonary disease (COPD) are at increased risk of Achilles tendon rupture. This risk is further augmented in the setting of an acute COPD exacerbation in which antibiotics may be indicated, namely fluoroquinolones. This case concerns a 76-year-old man who experienced simultaneous nontraumatic bilateral Achilles tendon rupture during an acute COPD exacerbation. Treatment was conservative with analgesics, activity modification, and bilateral controlled ankle movement boots...

Chronic obstructive pulmonary disease (COPD) affects nearly 6% of Americans. Routine screening for COPD in asymptomatic adults is not recommended. Patients with suspected COPD should have the diagnosis confirmed with spirometry. Disease severity is based on spirometry results and symptoms. The goals of treatment are to improve quality of life, reduce exacerbations, and decrease mortality. Pulmonary rehabilitation improves lung function and increases patients' sense of control, and it is effective for improving symptoms and reducing exacerbations and hospitalizations in patients with severe disease...

We aimed to test the association between serum lactate dehydrogenase (LDH) and its isoenzymes and treatment outcomes during hospitalization for acute exacerbation of chronic obstructive pulmonary disease (AECOPD). Thirty-eight AECOPD patients were recruited from a tertiary hospital from December 2017 to June 2018. Serum LDH and LDH isoenzymes were measured on venous blood collected at admission. Treatment outcomes included duration of hospital stay, initiation of non-invasive (NIV) or mechanical ventilation, initiation of antipseudomonal antibiotics, change in empirical antibiotic treatment, need for intravenous corticosteroids or methylxanthines, and percentage of change in C-reactive protein from admission to the third day...
